Kafka, 25, was drafted in the fourth round by the Eagles in 2010 but attempted just 16 passes, all last season. His release leaves Trent Edwards as the No. 3 quarterback behind starter Michael Vick and rookie Nick Foles.

Hanson, 31, played the past six of his seven NFL seasons for the Eagles mostly as a nickelback. He had 30 tackles and four passes defensed in 16 games last season, including one start.

He has appeared in at least 12 games in every season since 2004, when he broke into the league with the San Francisco 49ers.
